2-point reading : The plotter reads two regstraton marks n the X-axs drecton (ponts 1-2) and corrects the tlt n the
X-axs.
3-point reading : The plotter reads the ponts at the rght angles of three regstraton marks (ponts 1-2 and ponts 1-3),
corrects the tlt n both coordnate axes and then performs dstance adjustment.
4-point reading : The plotter reads the ponts at the rght angles of three regstraton marks (ponts 1-2 and ponts 1-3),
corrects the tlt n both coordnate axes and then performs dstance adjustment. The addton of the
coordnate values of pont 4 enables even more precse axal tlt correcton and dstance adjustment.
(1) Select MARKS as the regstraton mark mode, and then select the number of ponts for readng. (See Secton 4.2,
"Settng the Regstraton Mark Mode".)
